Hydrogeology of the Northern Gezira Area, Central Sudan
aquifer transmissivity hydraulic conductivity chemical analyses hydrochemical composition
2015/8/6
The aim of this study was to determine the hydraulic properties of the aquifers, evaluate the chemical characteristics of groundwater, and construct a water level and hyrochemical maps. Jacob’s, and T...
Runoff formation in a tile-drained agricultural basin of the Harz Mountain Foreland, Northern Germany
hydrograph separation hydrological tracers isotopes dyes groundwater drain sampler
2015/2/4
By taking two different tile-drained agricultural basins with porous aquifers in the lowlands of northern Germany as examples, it is demonstrated with an integrated study approach that this type of ba...

The Importance of Refreezing on the Diurnal Snowmelt Cycle with Application to a Northern Swedish Catchment
Importance of Refreezing Diurnal Snowmelt Cycle Northern Swedish Catchment
2009/10/28
A method for including night-time refreezing of the top layer of a snowpack in
the degree-day method for computing daily snowmelt rates is presented. It is
found that during days of large diurnal te...
